[PATCH 10/92] NAN: Add pairing capability indication attribute to NAN IE

[Andrei Otcheretianski]

From: Avraham Stern <avraham.stern at intel.com>

Add a function for adding the NAN pairing indication attribute
to the NAN IE. Currently only the Device Capability Extension
attribute (DCEA) is added, more attributes will be added in later
patches.
